effect, and the camb',

the front end thereof; g Ymer being provided with the 'usual half-cock7 Ward after the cam. and its lever have ceased to operate th ereon'. This bar, considered purely as a locking-bar, may be variously formed and still serve for lockin g and unlocking purposes; but it should have three contact-surfacesfone for being engaged by the spring c2 on luga for moving it forward, one for occupying the recess ct', and'another with which the cam b', engages. As'seen in Fig. 4fth'e'bar is adapted for a double gun, the lever Gr, its pin, and cam occupying avcentral positionon a line which separates the twol barrels. The bar is shown the lugs a. If desired only for a locking-bar, itis so housed within the breech as to be oapableof only such longitudinal-'movement as will'be requisite for entering and leaving the lockingreoess a. In such case, however, the spring a2 may be dispensed with, if notdesiredfor its cushioning operated by lever G, be then wholly relied upon for causing bot-h the locking (forward) andthe unlocking (rearward) movements of the bar F, the cam-slot therein in such case being no of the am, so that the latter 4will properly engage with both ends of said slot.

1 am aware that sliding locking-bars have heretofore been so combined with tilting hammers that the latter would be cocked by the rearward movement of the bar, and that levers of various kinds have been so combined with sliding lpekingfbars andtilting hammersv for moving said bars rearward and simultaneously cooking said tilting hammers. As employed by me, upon as a cooking-bar for automatically cockin g or setting the sliding hammer for firing, and therefore it is made longer than would be requisite for the purpose of locking the barrel imposition, and is also so mounted as to have the additional longitudinal movement requisite for its operation as a cocking-bar. It will be understood that but 011e sliding bar is emplo'yed, whether withone or two barrels.

The rear end of the bar 'F is in line with and arranged t'o abut, during its rearward movement, with a downwardly-projecting arm, c5, vupon the sliding hammer (or hammers) C near and the sear of the hamarrangement, the slight rearward movement of the bar F, operated as a locking-bar, also For automatically setting thelia-mner at lfull-cock I employ with the bar F a.V rocking cam, H, mounted in a recessin the under side of the front part of thebreech upon alateral pin, and

cam engages with ing-bar projecting from the lower side' of the barrel or barrels. Upon the rear edge of lug d is an inclined cam-surface', d', near its lower end, which-engages'with the front arm of the rocking cam, and the rear arm of said the front end of the lockat dz. The contact-surfaces of lug d, cam H, and the front end of the bar at d2 are so shaped and proportioned toeach other as a hinge-lug, d,

' movement,

longer than the swing thev locking-bar is also relied4 to secure a smooth easyactioinwhereby, when the barrel is tilted, the hammer is fully cocked, and so that when the barrel is in its locked position the bar in its forward movement, actuated by the spring a2, may readily return' the rocking cam to its normal position. rlhe einployment of the rocking cam in this combination is desirable; but the rearward movement of thebar may be attained by omitting the rocking camas a separate element, and providing'the rear edge of the lug d with-an outwardly-curved cam-surface, so that it will operate as a cam for engaging directly with the front end of the bar; Yand therefore L do not limit certain portions of my invention to the employment of this precise rocking cam as a separate element, but claim as a feature of invention the sliding hammer and the sliding, bar moved rearward. for cockin g the hammer by a earn actuated by the barrel in its tiltin g whether said cam be a rockin g cam, or whether it be formed upon the 'lng d, as indicated. Should the rocking cambe omitted, it would` be desirable to provide the front end of the sliding bar witha friction-roller for smoothly engaging with the cam-surface, as heretofore with sliding bars arranged to cooperate with tilting hammers.

The locking-of the barrel maybe effected by various means heretofore known independently of the sliding bar, and the latter, with Vthe rockingeam,relied vupon solely for setting the sliding hammer at full-cock, and the lever and cam b' relied upon for setting the hammer at half-cock. Thel cooking of the sliding hammer may also be'efected by other means well known, and the sliding bar, its cam, and lever relied upon` as a half-cockin g and barrellocking device. f
